London Commercial Roofing serves St. Thomas and Elgin County — the manufacturing plants, warehouses, and commercial buildings that give the Railway City its industrial backbone. We're roughly 30 minutes north up Highway 4, close enough to respond fast when a plant roof starts leaking over a production line.
St. Thomas has always been a working, industrial city — and it's growing fast, with the massive EV-battery manufacturing investment on the south edge of town bringing a new wave of large-footprint industrial buildings. That means a lot of big flat roofs: manufacturing plants, distribution warehouses, and the commercial blocks along Talbot Street and out toward the Highway 3 and Sunset Drive corridors.
Large industrial roofs have their own demands — long membrane runs, heavy rooftop mechanical units, and drainage that has to move serious volumes of water. And because St. Thomas sits on the high ground above Lake Erie, roofs here take strong, moisture-laden wind off the lake, especially in winter. We spec and install TPO and EPDM single-ply systems sized for that: heat-welded seams, proper insulation, and flashing detailed to survive the freeze-thaw.
